Sure, living with the nuisance of the advertising and UI clutter is an option, as I said. But the fact that they were relatively minor nuisances compared to eg. Windows 11's BS doesn't change the fact that they were still unwelcome and unnecessary and disrespectful.

I don't think there's anything radical about my stance that a new toolbar button showing up—with advertising calling attention to it—integrating a proprietary service into my open-source browser is inappropriate behavior on Mozilla's part.
